    It's fine when it works. Unfortunately, it rarely works in the past couple months. It won't pull emails. Once in a while, it will pull emails from a day ago. Refreshing doesn't work. Syncing accounts doesn't work. Even reinstalling the app doesn't work. Plus- when you reinstall, an error occurs when you try to add accounts back. I'll keep an eye out for an update but these recent releases (4.2111.1 - 4.2111.2) are worthless.

    I use it for school I have an outlook account that I sign into and without logging into my computer I can take outlook wherever and whenever. Their are downfalls using this app and one of them is........that if you have a signature that you put in some emails and others you don’t there is no way to put a signature in your email in Outlook app which I don’t mind but then again I thought all your capabilities that you have online or app on computer you would have in the app for your phone. Another downfall I think is that you can’t say a email is “low important or high importance” I again for me that’s not super important but it would be nice to have on the app for your phone. There are plenty other things you can’t do on the app for your mobile device but you can do on the desktop app for your computer or laptop or pc. Other than, I like using the app and reading emails that come in without running to my computer to reply or even just read a single message I can be away from my computer and use my phone while I’m on the go doing other things that are little more important than sitting at home waiting for a email to come in thinking that’s the only way I can respond and receive messages from Outlook.

    I’d give it an 4.5 if I could, but it’s not a four. I’d like it if it was easier to figure out at first how to access other folders such as trash and drafts—or maybe I’m just slow. I like how you can change what the slide function has—I have it set to delete which is super helpful and I wish the apple mail app had. I use both apps with Microsoft OutLook for my school email. I also like the computer version as well. Both versions of the app can (and do) remind me of events I have in my Microsoft calendar (I forget their name, if it has one). This is really helpful as my high school is using teams during the whole pandemic-so I get reminded before school starts, towards the end of classes I dislike, and before lunch ends that I have class which is really helpful. I’ll also mention that you can turn this off—for one or all events—and change the amount of time beforehand that it reminds you at (15 or 5 minutes beforehand for example). I still will use google as my main email because I already am—it isn’t better enough in the ways it is to change. I don’t think it is worse per say that google/apple email apps/websites. Hope this helps!

    This is the worst app that I have on my phone. Typically I don’t keep apps that I absolutely hate, but since I have no alternative to using this horrible thing, I haven’t removed it. This pathetic thing has caused problems for me professionally. It takes less time for me to boot up the computer and check my calendar and then it does for me to even make my calendar showing this out. Hoping out an email literally takes as long as it would to write a letter and put it in the mail. Smoke signals will be better than this app. I can’t even open my calendar to understand what kind of meetings I have for the day because this app loads every single calendar I have shared to me and freezes every time I click a button. This is horrible. Don’t know why Microsoft insists upon upgrading things to be absolutely terrible. Even more I can’t understand why the entire professional world forces everyone to use Outlook. Gross. Even worse, it’s been out for a year already and you’ve done nothing to fix it, it’s gotten worse if anything. I’d be fired if I was this bad at my job.

    It's a very good app and makes small improvements over time. I still need you guys to improve the search function to make it as good as the desktop version where you can search by subject and many other options as well as search emails related to a specific email. Also, add the "teams meeting" option when setting up a new appointment like there is with Skype. Change those two things and you get 5 stars from me.

    Another update and another function goes down. Now every time I want to add an event to my calendar, the app just shuts down. I guess it's an improvement on the app crashing after I open it, but still renders that useless in a mobile environment. I have cleared my cache, uninstalled and reinstalled the program, and restarted my phone. It might work once, and then it just fails.

  • Disjointed Functionality Jul 23, 2020

    By Phanoteus
    It seems that Outlook routinely "forgets" your mail accounts, even when using Microsoft's own Exchange-based accounts (Outlook, Hotmail). Why is this? Why does Outlook have to refresh all of your mail locally almost every time you open it? There will even be a numerical badge indicating unread messages, but when you open Outlook, you will be notified that Outlook has "found" accounts on your system (accounts that you have, of course, already added to Outlook) and you will be prompted to add these accounts again. The standard Apple iOS Mail app actually seems to manage Microsoft's own mail accounts better than Microsoft's email app. How can this be? Is Apple doing sometime here to hobble non-Apple email apps (as they do with non-Apple mobile browsers) or has Microsoft not been able to figure out how to develop native iOS applications? I'm inclined to think it's the latter, because other non-Apple email apps do seem to be able to retain email account continuity. It's a shortcoming only for the Outlook email client. I keep trying to use Outlook as a mobile email client for my Microsoft email accounts and I always end up uninstalling it and reverting to the Apple app or some other third-part email app. It's a shame, really. Google's Mail app works pretty well for Gmail. Microsoft's Outlook app doesn't work well for Microsoft email. What's going on here?

    Can check my email so the basic works but have to read/delete the same emails over and over. Anything you delete Outlook tries to put future correspondence into junk mail. so now i have to check my junk mail everyday to make sure my real mail isn't in there. happens daily. needs serious updating. looks decent but works subpar.

    I wanted to like this app because I need it for my business. I tried everything I can find recommended online to get it to work properly. No help. It doesn't receive emails for hours (and often not at all) unless I reset the app. It does not notify me of anything despite having all notifications turned on. The contacts randomly sync or don't sync, depending on the weather, I guess? It's just super glitchy. Hoping Microsoft fixes those things. After that, I think I will love this app.

    Recent update has made App unusable. Prior to that I'd used outlook successfully for many years. Tried uninstalling and reinstalling, it won't reload properly. Spent hours trying to sort it. Now I'm trying to completely remove it from my android phone but of course it doesn't want you to be able to do that either. I've now downloaded Yahoo, took seconds and went smoothly, I'll be using that from now on.

  1. Do more with less! Outlook for mobile devices gives you full access to Microsoft's office tools on the go
  2. Compatible with Microsoft Exchange, Office 365, Outlook.com (including Hotmail and MSN), Gmail, Yahoo Mail, and iCloud
  3. Bring all the mobile apps you love under the Outlook umbrella: Facebook, Twitter, Instagram, Evernote, Trello, Slack, and more

  • Very simple email app Aug 8, 2020

    By nammai25
    I have used numerous email applications in the past, but Outlook really is the best of them all, period. There are a lot of features here that I can’t fathom in either Gmail or Yahoo Mail, such as calendar integration, syncing with multiple devices (including computers), and a simple user interface. While I heavily use Gmail on a day-to-day basis, I think that Microsoft really pays off when it comes to this functional app. I don’t want to screw Redmond if they have missed anything worthwhile or important, but I am happy with the work that the Outlook team has put into it. In conclusion, please download this app if you can, and enjoy a simple, refreshing email experience. (The only flaw I have encountered so far? Well, as far as I can tell you, there have been a lack of features from the web app of Outlook, and you have to sign in there to access them. Only the mobile app has several features. But, otherwise, as I have said, I am content with that.)

    Been using this app for 6 years on 3 different Samsung Galaxy phones, current being a Galaxy Note. Yeah, it’s not the full-featured desktop app, nor is it meant to be - Its still useful for receiving, sending, and replying to emails. Plus, you can send attachments. Notifications work. Running 4 email accounts including one Exchange account - that means adding accounts works. I get all my emails as they arrive, and they are sync’d with my Outlook desktops and laptops. And YOU CAN see all unread emails from all accounts. Works here.

  • So good in some areas and 1990 in others. Dec 11, 2017

    By NebraskaJer
    Hello, I love the outlook app and I need to use it on a day to day basis. Some of the items like calendar events and sending notifications is great in parts but lack in editing. First off. Why is there no copy and paste in Outlook. I had a whole email typed up and I needed to input a link. So what would I have to do? Copy and paste it in. Nope. I have to go to safari and click share and then outlook so I can send a link in outlook. Well then when I get in outlook I have to retype my message or just paste in the other one right. Nope. Paste does not work from previous to new message. So I have to manually copy something by hand. Link or original message. Come on Microsoft. Make copy and paste work the. You get a solid 4. Add some polish and sub folder notifications and some editing tools you will have a 5 Star app again. Please fix these little flaws. You have office and should be able to make a solid app. Now let’s make it happen. Thanks.

    This email app is great except for one thing: the email address autocomplete list. Email contacts seems to keep a record of every email address ever seen, bogus or not, in my contacts list or not, whether I've emailed to them before or not, and will display them in the To: address when composing an email. Not only that, when I use the share button in *any* other app, it manages to display some of these useless email addresses at the top of the suggested sharing list. And there is no way to get rid of them!

  • So Much Better Than the Native iPhone Mail App Aug 7, 2020

    By markedwjohnson
    I had been meaning to try the Outlook app for iOS for a couple of years, moved to O365 and MS Intune necessitating my move to Outlook for iOS; fine by me. The learning curve has been minimal. I haven’t found a way to move between emails without going out to my inbox or other containing folder, but I haven’t had time to google that, either. I just wish there were up/down arrows within an email allowing me to move up/down a message within the parent folder. I like that it feels more professional in UI appearance than apps aimed at consumers in general; other than the one feature I complained about it lacking above. I haven’t tried this yet, but it appears that I can even set my OOO message, or update it, from the app! Now THAT’S a level of integration with our Exchange server that wasn’t even possible with any other mail app on the iPhone or iPad. That is awesome! I can’t wait to find out what other little nuggets it has that I haven’t discovered yet!

  • Great app, but ... May 7, 2020

    By ebassily
    When I delete or archive an email it takes me back to the list view rather than moving on to the next email. I should at least be given the choice of whether I like to move forward or go back to the list. Making contact pictures appear (as advertised in app pics) beside each email from them is a pain. I have been trying to make it happen for quite a bit now without success. I even copied many of my 6+k contacts to Outlook on my Mac to be on the Exchange server rather than on iCloud but it didn’t work either. I think the problem is that Outlook insists on keeping itself isolated from iOS apps and their SDKs. It doesn’t show contacts from iOS although it does show iCloud calendars. The app even doesn’t have a Contacts tab like its macOS counterpart. There is a Mail tab as well as Calendar and search tabs, but no Contacts. Even the Contacts section on the macOS app is far inferior to Apple’s stock Contacts app.

  • Great replacement for Mail, needs only one fix Jul 29, 2020

    By rebg23
    Overall I really like outlook and find it is equal to or better than Mail in virtually all respects. The reading function works amazingly well, and the overall layout and functionality is excellent. The one function I don’t like in Outlook and wish work like Mail is the undo function when I am filing and moving messages into folders. In Mail, if I move a message to the wrong folder, I can just shake the phone and and trigger the undo function to reverse the move, even several seconds later. But in Outlook, the undo is provided by a software button that appears for only a couple of seconds at the bottom of the screen. If I don’t click the button right away, the ability to undo has passed, and then I have to hope I can find the message in the wrong folder and manually re-locate it etc. Not a deal killer by any means, but if that were fixed, I would give it six stars.

  • User friendliness and efficiency needs improvement Oct 13, 2019

    By ritzoni
    So when you use gmail you can do a search and it will bring up emails specifically from the word you searched. For example, if you search for Apple Pay it will pull up emails from Apple Pay first. If you do the same search in outlook it will give you all emails that include those words as the sender, subject, mention, etc. This means you have to navigate through a list of unimportant emails to get to the one you want if you don’t give up in utter disappointment in the process. If that’s not frustrating enough when you write an email and it goes past a certain line you better hope you can type really well because you won’t be able to see past that line. I would have to stop scroll up and check the sentence, correct it blindly because it toggles back down where it can’t be seen and continue typing. So I started writing in other apps like gmail and forwarding it to outlook or doing a copy paste and forwarding it to my recipient if it was a longer message. That is not how I want to send my emails but outlook hasn’t seemed to be able to figure out how to make it work. Thus I have several apps for emails. Ugh

  • The App is Ok Aug 1, 2019

    By Bethdoodle
    The app has worked great since I got it last year, especially for school. But recently it’s stopped sending me notifications for some emails which has caused me to miss several emails and dead-lines. It’s too late for me at this point so please fix this issue. I don’t know if it’s because I had 2 inboxes from 2 different school emails or what, but this problem has caused me a lot of stress and I’d prefer it not happen in the future. Edit: The issue that I believed was originally occurring is not the only one. It appears the reason I am not getting notifications for emails is because these emails aren’t appearing in my inbox until days later. For example, several emails I received on the 30th of July did not appear in my inbox until today. I did not get any notifications for any emails on that 30th. This is really frustrating because I’ve received emails from university faculty who have been sending and requesting information and it is really creating a huge hassle for me and causing more stress than is needed. Maybe this is something I need to talk to my school about? If it is please let me know.

  • Extremely basic, can’t organize mail Mar 3, 2020

    By ggianop
    This is a terrible implementation of outlook. It’s only good for basic reading & writing of simple emails. I can’t manage folders other than the ability to create new folders at the top level of the folder hierarchy. I can’t create a hierarchy of folders. God forbid you used Outlook for windows to create a folder hierarchy in your mailbox; it can’t be edited, new folders can’t be created within this hierarchy, and there is NO WAY to delete any folders in this app. (The native Apple Mail app is more functional with this regard than MS’ own app.) The only other reason I’d use this app over Apple Mail client is to retain the ability to create other types of outlook / exchange documents in folders. But, alas, the authors have removed this feature too. No more notes, postings, or other document types. So now I have to email things to myself and move them into folders when I want to use exchange to organize my online documents & notes; and that means sending notes through email which is often a security risk I was never exposed to before. But, then again, since I can’t do folder Mgmt, I’m better off using Apple Mail so I can at least manage where and how I store my info with my folder hierarchy.

  • Only one month of storage? Seriously? Jul 26, 2020

    By Jeff DeWitte
    I don't know about the rest of you but I use this app on my iPhone for business. It has a very limited amount of storage space and I received quite a few emails. I'm only able to access emails dating back one month. No help from tech-support and I see that many others have suggested an improvement to the developers. No response. Typical Microsoft behavior. They will always think they're better and smarter than anybody else. Part of the problem is that they don't listen. That arrogance and lack of adaptation to changing behavior is what is making their company fade. The only way to access these older emails is to use the web-based browser on my desktop. This is an absolutely ridiculous alternative just simply having an app that would allow you to use local storage on your device to archive and back up your emails for easier access on the go. I'm not sure why they have such limited storage. I have tons of free storage using my yahoo email dating back to the late 90s! Absolute crap. If you can avoid this ridiculousness please find another email client to serve your business needs. And Microsoft - I hope you burn in hell.

    Outlook needs to make it easier to identify emails that are NOT junk mail. It's already easy enough to identify junk mail that's a threat. Microsoft quit trying to control everything. We are fully capable of controlling our own junk mail. Get rid of your server-based filtering system and allow your customers to do it through the app. We need to have the CHOICE not YOU, you send important emails of mine to the junk folder all the time. I have to check the junk folder Daily for important emails.

  • The only thing worse than this app is their customer service Jan 4, 2019

    By Coppercosmo
    I’m trying to use this app to access my work email from home. The app has continually deleted my entire inbox for no consistent reason I can figure out. I will open a new email and it will delete the email while I’m reading it and then my entire inbox. My inbox on my work computer will still be intact, but any email I attempted to open in the app will be missing. When I contacted customer service through the app they told me it simply wasn’t possible that the app was deleting emails and never responded again. When I attempted to email customer service on my work computer it said their customer service email address is undeliverable. I missed a very important email from my boss this morning while out sick, and even drove into work to try and see if I could access the email there to find nothing. I very well might loose my job over this and their customer service frankly does not care. If you can avoid using Microsoft (which I know is impossible) do all you can to stay away from them. They are a heartless company, and their substandard products will not only make your life hell, their customer service department seems to get joy out of your pain. If I could give them zero stars I would!
